X-ScaleSolutions is pleased to announce the release of X-ScalePETSc to accelerate HPC applications that use the PETSc library. Our X-ScalePETSc library is a version of the PETSc library (https://petsc.org/release/) co-designed with the MVAPICH2 MPI library. 

PETSc, the Portable, Extensible Toolkit for Scientific Computation, includes a large suite of scalable parallel linear and nonlinear equation solvers, ODE integrators, and optimization algorithms for application codes written in C, C++, Fortran, and Python. It is primarily developed and maintained by the Argonne National Laboratory. It is used by more than 30 scientific toolkits/libraries to simulate engineering problems in a variety of domains including nuclear physics, fluid mechanics and solid mechanics.

Features of X-ScalePETSc 2024.4 release include: 

• Optimized small to medium message intra-node CPU-CPU communication for MatMult — the PETSc matrix-vector multiplication kernel widely used in its iterative solvers and preconditioners.
• Applicable to MATMPIAIJ matrix type and its subclasses.
• Based on PETSc 3.20.4 and MVAPICH2 2.3.7.
• No change to the PETSc API from the PETSc user side. 
• Up to 13% MatMult kernel-level benefit and 10% application-level benefit for small problem sizes.
• Flexibility to work with third-party libraries with PETSc
